ELECTRICAL LOAD BALANCING CALCULATION

 ⚡ ELECTRICAL LOAD BALANCING CALCULATION

❓ How do you balance electrical loads across three phases?

Electrical load balancing distributes single-phase loads as evenly as possible across the R, Y, and B phases to reduce current imbalance and improve system performance.

📐 FORMULA:

Average Phase Current = (IR + IY + IB) ÷ 3

🔹 EXAMPLE:

R Phase = 80 A

Y Phase = 70 A

B Phase = 60 A

Average Current = (80 + 70 + 60) ÷ 3

✅ Average Phase Current = 70 A

📍 BALANCING ACTION:

• Transfer suitable single-phase loads from the highest-loaded phase to the lowest-loaded phase.

• Recheck phase currents after redistribution.

• Check neutral current and voltage imbalance.

⚠️ Actual balancing must consider load demand, power factor, harmonics, conductor ratings, and applicable standards. Work must be performed by a qualified electrician.
